What Type of Crusher Is Best for Primary Crushing?
Primary crushers reduce large run-of-mine material, such as rocks and ore lumps, into smaller sizes for further processing downstream, whether that be transport to additional crushers or to a wet processing plant. It is the first stage in the crushing process that can sometimes include secondary, tertiary and even quaternary crushing …
Trends in the crusher market and operational challenges
As researchers at the Chalmers University of Technology in Gothenburg, Sweden, have established, the OEE for cone crushers in mineral processing and aggregate productions is often very low (< 50 %) prior to optimization. The explanation is an unfavourable crusher feed or inadequate crusher control. Crusher feed should be as good and evenly ...
